GLASS INDUSTRY.
Glass from the earliest historic
ages has been favorite medium
for the expression of beauty. The
fluid character of the original sub
stance permits it to be nodded to
an infinite variety of forms, and
the most delicate shades of color
ing may be infused through its cry
stal clearness SO as to adapt it to
the luxurious uses of the table.
The highest development of art is
in the production of cameo glass.
Evidences of this art in its perfec-
ton are very ancient, and even in
the beginning of the Chistian era
very beautiful and expensive articles
of glass were in use. AT that time
also glass in its commonest forms
was cheap article. At % b. {. a
cup and saucer of glass could be
bought at Rome for money equiva
lent toour cent. Illustrating the
other extreme, it is historically mar
rated that the Emporer Nero paid 4
sum equivalent to S25O,OOO for two
cups of moderate dimensions. Win
dow glass did not appear until the
third century of the Christian era,
and il did not come into general use
until the fifteenth century. In 1861
only the principal chambers of the
Kings palace in England had win
dow glass.
Egypt offers the earliest possible
evidences of glassmaking. Glass
bottles containing red wines are
said to be represented on the monu-
ments of the fourth dynasty, more
than 1000 years ago, and in the
tombs of very early period the pro-
cess of glass-blowing is represented
in an unmistakable manner In the
time of the Roman Emperor Had
rian, among the chief industrial oc-
cupations of the inhabitants of Alex
andria is mentioned glass-blowing ;
and during the reign of Aurelian,
in the third century, glass formed
a part of the Egyptian tribute,
showing that it was then an article
of manufature in Egypt. The del
icate coloring of glass, that adds so
much to its beauty, was known in
ancient times. These colors are
produced by mixture with metals ;
for instance, blue is produced by
cabalt, green by copper and rose or
ruby by gold. The great site of the
manufacture of glass in the middle
ages was Venice, and its articles OF
manufacture were exported all over
the world. The glass trade of Venice
has been superseded by that OF
England and Germany.
Silicon, of which there is ninety
per cent. in good glass sand, is the
principal ingredient in glass. Lead
enters into the superior qualities OF
glass, giving it clearness and bril-
liancy, and the musical ring of 9
glass article only comes from bad
glass. Crystal glass is bad glass
which is also termed flint glass
Only lead glass can be cut. Lime
is now greatly used in the manu-
facture of glass pressed glass articles
being made of lime glass. In it'
manufacture the United States Ira:
anhdvantage over other countries ,ol
account of its greater talent for thu
use Of machinery. Pressed glasi
articles are now exported from th'
United States to all parts of 'th'
world. The value of our exports o
glassware grew from $65S,051 il
1877, to 1888, ,504 in 1887, of which
the bulk was pressed glass. In 1SS
we exported 1885 worth of win
dow glass. While the eastern par
Of this country was formerly tn
. seat of the principal glass industry
, it has moved west of late years
/ owing largely to the backwardnes
: of the eastern manufactures to tax
: up the making of lime glass. st Loui
, is now an important glass manu-
$ featuring center, but the creates
amount of business is done in tn
Ohio valley, of which Pittsbur
and Wheeling are the chief glas
towns. The natural gas Of thi
e section has given the glass industr
a great impetus. Heavy plate VIII
dow glass is manufactured largcl
S in the West, but the glass used j
y the east is mostly imported fror
